16.When the burner ignites the display should read "HI-FLAME " at the left of the display. Loosen the nut on the main regulator and turn screw in, to increase pressure and out to decrease pressure. The pressure gauges should be set at 10-15 lbs. for LP units, or 4-6 lbs.. for natural gas units. (use the charts on the following pages to set pressure)

17.Press the "PROGRAM TEMPERATURE" but- ton to change the high limit set point. Press it again to change the "CYCLE SET POINT". (hi- lo units only)

18.Decrease the "CYCLE SET POINT TEM PERATURE" until the heater cycles to low flame. (hi-lo units only)

19.Open or close the low cycle ball valve until the gas pressure is 3-5 lbs. for LP, or 1-2 lbs. for natural gas. (hi-lo units only)

20.Increase the cycle set point to return to high flame.(hi-lounitsonly)

21.Watch heater run several minutes to make sure it cycles between hi and lo flame or on and off properly.

22.Hi-flame pressure should be adjusted so ple- num reaches cycling temperature easily.
